I wholeheartedly recommend McNally's. I've used them twice, once for duct cleaning and again when my furnace broke down. They diagnosed an problem on a furnace that another company said would cost over a grand to fix. They're prompt to respond, show up when they say they will, and do good work for an honest price. Doesn't get much better than that.

We called for an emergency replacement of our furnace that stopped working and they not only beat every estimate we got they were out there within the hour to do the job. I can't say enough about what a great experience I had with this company.
